I don't know about DL, but the only place I can think of with chicken strips at CA is the fish/chips place on the pier (they're really good!). I must not be that big of a fan of chicken strips though cause I don' tremember them being everywhere at WDW either
I can think of lots of places that I know for sure DONT have chicken strips at DL/CA, so I guess you might be right. The places I can think of that MIGHT have them (though we don't eat there) are Hungry Bear and that Tomorrowland place where Buzz is.
